To all whom it may concern 7 Be it lmownthat I, EDGAR J. VASEY, a

citizeu'ot the United States, residing at Cozad, in the county of Dawson and State 01' Nebraska, have invented certain new and useful, Improvements in Discharge Means for Silos, &c., of which the following. is a. specification.

The object of this inventionhas been to devise improved means for facihtatmg the removal of ens lage trom SllOS.

The invention comprehends the provision at intervals verticali y of the silo of openings by which access ma y be had to the contents of the container as the ensilage therein is gradually reduced in quantity by removal. Located opposite to the said openings is a vertically movable carriage mounted on rails or guides and supporting a chute adapted to be positioned by the said sup port opposite a selected one of the openings in the wall of the silo. In association with the chute is a hopper to receive the material passing alongthe chute and with which hopper is connected a conduit ot extensible structure preferably and adjustable to assume positions permitting of the discharge of the ensilage' or contents of the receptacle into a vehicle or other carrier as may be desired.

A completeunderstanding of the invention and the advantages of the same under practical conditions of service will be obtained on reference to the following description and the accompanying drawings in which Q I Figure l is a fragmentary View of the side of a silo of conventional construction showing the discharge means embodying the present improvements. .Fig. 2 is a sectional view vertically of the said means taken about on the line 2-2 of Fig. 1. Fig.

3 is a horizontal sectional view. Fig. 4 is a sectional view taken through the chute, the hopper and the upper portion of the conduit. dotted lines showing the chute in upraised position to pe mit the passing by way of the opening of a person, the. hopper being spaced quite a distance from the guides for this purpose.

A n the drawings denotes the silo and it is to be understood that within the purview of the invention the latter may be readily used in connection with containers other than silos such as large bins and even buildings utilized for storing grain or similar purposes. silo are located openings A. and through which openings the contents of the silo may be removed conveniently. Opposite the portion of the wall of the silo having the openings; A is a supporter carriage B mountedto operate longitudinally of rails or guides 2 carried by the supporting brackets 1-. The support B consists of a frame B .lOcated between the guides 12 and formed at opposite portions with the. curved arms 3 between the rear endsof which at the upper portion of the frame are mounted rollers 3' adapted to engage with the guides 2 at the rear of the latter. In like manner, at the lower portion of the frame l3" and intermediate the frontportions of the arms 3 and the guides 2 are other rollers 3'.

The latter rollers operate on thefront sides of the guides 2. Of'fstanding from the frame B, are the spaced downwardlyinclined arms 6 and the lower oitstanding arms Z), said arms being connected together by means of platesor bars Z)". The outer ends of the arms I) and 6 support a somewhat square shaped frame 0' which carries a hopper C thereon, the inner wall of the hopper being cutaway at the upper portion so as to read ily permit of passing into the hopper materials supplied thereto from the chute D.

The chute D is pivoted at its lower or outer end to the frame 0 so that the chute may be moved into .an approximately vertical "position ,as shown in dotted lines in Fi g. at,

or may assume the inclined position shown in full lines wherein the chute ,extends from' At intervals vertically of the:

the hopper C over to one of the openings A of the silo. Owing to the fact that the hopper C is spaced a considerable distance from the wall of the silo A by the special construction of the support or carriage B, it is apparent that the. operator may readily climb a ladder and pass through the space between the arms bandsb by raising the chute D 'into the dotted line position in Fig.4. M.

The location of the rollers 3 operating along the guides 2-issuch as to render the movement of the carriage or support'B very easy and for the purpose of efiecting such movement in order to position the chute D opposite any desired one of the variousopenings A suitable hoisting means is provided. The hoisting means preferably 'consists of a rope 6 connected to the upper portion of the frame B of the support B and ing a number of telescopic sections and tlfis passing over a roller carried by an arm 5 projecting from the silo. The rope or cable 6 then passes arounda double pulley 7 on the arm 5 through the wall of the silo and over a pulley 6. By exerting a pull on the -rope 6 it will be apparent that the carriage which supports the hopper G are spaced hangers 4 to the lower extremities of which is pivoted a conduit E. The conduit E is preferably of the extensible type comprismay be shortened or lengthened as required.

An operating rope e is connected to the lower portion of the conduit E and passes over a pulley 8 on the arm 5 thence rearwardly around the pulley 7 and over the pulley 6' into the silo. The ropes and 6 are therefore capable of-manipulation by the operator Within the silo, this being advantageous in the operation of discharging material from the latter since the chute-D may be readily positioned opposite the openirgs A as the level of the contents in the container is lowered. If desired the connection intermediate the conduit E and the support I} may be'such as to admit of an outward swingingof the conduit as well as Sidewise swinging.

Having thus described the invention, what is claimed as new is i 3 1. In discharge means of the type described, the combination of spaced verticalguides, a movable-support mounted to operate on said guides, said support comprising a frame having gu'idingmeans at opposite portions thereof engaging the guides above referredto, arms projecting outwardly from said frame, a chute pivotally supported by said arms at a point spaced from theguides whereby the chute may be moved into a vertical position spaced a considerable distance from-the. guides, the free end of the chute being movable into a position resting upon the frame aforesaid, and means for raising and lowering the movable support.

I 2. In discharge means of the type described, the combination of a silo having openings at intervals vertically of the same, guides at,

opposite sides of said openings, a movable support comprising aframe and supporting arms and mounted to move lengthwise of the guides aforesaid, aconduit carried by said support in spaced relation to the guides, and

a chute movably mounted on the said movable support so as to assume a position opposite a" selected one of the openings of the silo and supply material to the conduit, and

a connection between the chute and the mov able support permitting movement of the chute into a position spaced throughout its length from the guides, for the purpose described- 3 3. In discharge means of openings at intervals vertically of the same, guides'at opposite sides of said openings, a movable support comprising a frame and supportingv arms and mounted to move lengthwise ofthe guides aforesaid, a conduit carried by said support in spaced relation to the guides, and a chute movably the type \described, the combination of a silo having and also connected with the movable support to move the later longitudinally of the guides on which it ismounted.

4t. In combination, .a silo having openings at intervals vertically thereof, guides at opposite sides of the openings, a movable support mounted on said guides and comprising a frame between the guides, means -on the frame connecting the support'to the guides,arms projecting outwardly from the frame, a hopper carried by the outer ends of said arms in spaced relation to the guides, a conduit pivotally supported at its upper end by said arms, a chute normally received at its inner end within the frame aforesaid and supported at said end bysaid frame,-said chute communicating with the hopper above mentioned, a pivotal connection between the cnute and the hopper perm tting of movement of the chute into a vertical position substantially parallel with the silo, and operating means connected with 'the carriage and with the movable support and with theconduit for moving the same in relation to'the silo.

In testimony whereof I afiix my signature in presence of two Witnesses.
